How many of you buy BD movies without seeing them already?

Even since I jumped into the blu-ray bandwagon, I have been buying BD movies I have never seen before, taking a chance that it'll be a good movie. At times I end up selling it back to the retail for store credit so that I could purchase another movie. This gets pretty expensive having to spend $30 on a movie and later it just sucked then selling it back for only $10 or less. I'm more interested in buying a movie that I have never seen before then watching the movie over again.

Does anyone else buy movies without watching them before? Since BD movies take a long time renting at Blockbuster on-line, I'm craving for new movies to watch every week. My next purchase I'll be buying that I haven't seen would be Night at the Museum. Hopefully this will be a keeper
